1. 1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction

   University essay from KTH/Materialvetenskap

   Author : Josefin Mvele Svensson; [2024]
   Keywords : Non-metallic inclusions; electrolytic extraction; SEM; Icke-metalliska inneslutningar; elektrolytisk extraktion; SEM;

   Abstract : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and  the  content  of  non-metallic  inclusions  (NMI).  Achieving  cleanliness  is a  gradual  process  where all  the  steps  of  the  production  process  are  inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

3. 2. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Solal GAUDIN; [2023]
   Keywords : Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

   Abstract : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. READ MORE

4. 3. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

   University essay from Lunds universitet/Kemiska institutionen

   Author : Mohamad Abd Elwadood; [2023]
   Keywords : Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

   Abstract : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. READ MORE

5. 4. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik
